Just got our 22' TT last July. New to RVing. I recently had reason to check the health of the battery. No good. Bought a new one. Question: Is it better to leave it on camper hooked to shore power during cold weather storage or should I bring it in to the garage where temps rarely get to freezing and keep it hooked up to battery charger? It is an automatic charger - it automatically switches between charge mode and maintain mode. When the voltage drops below a preset level goes into charge mode. What's your advice?
